Despite being more common than any other planet in our galaxy, the solar system lacks a mini-Neptune. That means, to study these worlds, ...

To test the previous hypothesis that LHS 1140 b is a mini-Neptune, the researchers created a 3D global climate model, or GCM. This used complex math to explore different combinations of factors ...

A young planet named HIP 67522 causes violent eruptions on its star, dramatically accelerating the loss of its own atmosphere ...

Mini-Neptune planets are defined as smaller than Neptune, with Enaiposha even smaller. They are relatively straightforward to study because of the thin gaseous layers typically found on these planets.

This brings us to K2-18b, a mini-Neptune orbiting a red dwarf (M dwarf) star about 134 light-years away. The Kepler Space Telescope found it in 2015.

A mini-Neptune, as it sounds, is a gaseous world between the size of Earth and Neptune.A super-Earth, of which astronomers have found many intriguing examples, is a world ranging from some 30 to ...

TIDYE-1b could be mini-Neptune or super-Earth The fortuitous discovery, the researchers said, provides an opportunity for astronomers to learn more about emerging planetary systems and how they ...
